Mac OS X only: Send your office documents to the cloud in one click and swipe with Gdocsuploader. Place this bare bones application on your Dock, Finder sidebar, or desktop, then drag and drop word processing documents, spreadsheets, or PowerPoint presentation files onto it to add them to your Google Docs account. You'll need to provide your Google account username and password, of course, and when the upload's complete you get the option to open the doc in your web browser. Gdocsuploader is still new and a bit unpolished; expect a few Keychain prompts to get your files transferred. Gdocsuploader is a free download for Mac OS X only (works on Leopard for sure, Tiger usage not yet confirmed.)
